Perimeter trails are often not the most scenic or rewarding because you're basically hiking the outer boundaries of the park (w/ occasional views of nearby houses, roads, power lines, etc). Bowie is one of the nicest and most unspoiled parks in middle Tennessee. The park's perimeter trail, although really nice, is my least favorite, but there are so many adjoining "interior" trails that you can incorporate them into the perimeter route for a much more scenic tour.
The trail itself is great for hiking and running. I try to hike the premier trail 2 times a week. If you start from the parking area by Shelter 1 and enter the trail at shelter 2 you will have 2 very significant inclines. At the 2.5 mile mark just past the creek crossing you will start a 3/4 incline in elevation a few places steep mostly just long. Then at the end of the trail about 100 yards very steep to the top. Fast hiking, trail is an old fire road.
